MECHANICAL MOVEMENT.

Application filed April 26. 1918, Serial No. 231,007.

To aZZ whom it may concern Be it known that I, MARTIN 1V. MUEHL- IIAUSER, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Mechanical Movements, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to mechanical movements and particularly to apparatus of this character in which a reciprocable doublecam movement of one member in one plane results in a reciprocable movement of another member in a divergent plane and in which the movement is positively locked at the end of the actuation in either direction. More particularly, and as illustrating one of the applications of my improved movement, the invention herein later to be described and shown in the accompanying drawing relates to a new and improved mechanical movement utilized in connection with the operation of power presses.

The annexed drawing and the following description set forth in detail certain means embodying my invention, such disclosed means, however, constituting but one of the various forms in which the principles of the same may be utilized.

In said annexed drawings:

Figure 1 represents a side view of apparatus illustrating my improved movement, there being also shown a fragmentary portion of the frame of a standard type of power press to which my invention has been applied; Figure 2 represents fragmentary portions of the parts shown in Figure 1, the position therein shown being that when the members of the movement are in the extreme position opposite to that shown in Figure 1; and Figure 3 represents a horizontal section taken in the plane indicated by the line III-III, Figure 1.

Referring to the annexed drawing, there is disclosed a suggestion of the frame 2 of a standard power press to which my improved movement has been applied, for purposes hereinafter fully explained. This movement, in the specific embodiment thereof herein shown, comprises a rod 8 adapted to be vertically reciprocated in brackets 9 secured to the frame 2. This rod is formed at one end with an enlarged portion 8' pro- Specification of Letters Patent.

vided with a pair of plane exterior surfaces 10 and 11 serving as cam surfaces. Pivoted to a member 21 in turn pivoted to an angle plate 17 supported upon the frame 2 is a horizontally-reciprocable rod 13 normally held in its outer position by a spring 14". The sald horizontally-reciprocable rod 13 is formed with an enlarged end portion 18 comprising a shell-like member formed with interior cam surfaces 14 and 15 complementary to the surfaces 10 and 11 of the end portion 8 of the rod 8. Complementary curved surfaces 12 and 16 are also formed upon the rods 8 and 13, respectively.

It is evident from the foregoing descript1on and an inspection of the drawing that. when the horizontally reciprocable actuated by any suitable source of power from the position shown in Figure 1 to the position shown in Figure 2, this movement of the rod results in a double cam movement between the surfaces 10 and 11 and 14.- and 15, and that a downward vertical movement of the rod 8 will result.

The source of power, shown in the accompanying drawing as one means of effecting the reciprocating movement of the rod 13, consists in an electric circuit within which is contained a magnet 18 suitably supported upon the angle plate 17, a suggestion of the circuit being indicated by the ordinal 19 denoting one of a. pair of lines connected to one of a pair of wires from a lamp line and the ordinal 20 denoting the other of said lines connected to a suitable contact finger (not shown) forming part of the circuit, the lines 19 and 20 both being connected to the terminals of the magnet 18, the other lamp line wire being connected to a second contact finger (not shown) adapted to contact with the first named contact finger to close the circuit. Carried by the pivoted arm 21 is a member 16 adapted to be attracted by the magnet 18 when the electric circuit is completed and the magnet is energized. It is evident, therefore, that the attraction of the member 16 by the magnet 18 will result in a straight line movement of the rod 13, which, through the cooperating action of the cam surfaces 10-11, 1415 will result in a downward movement of the rod 8; and, conversely, the release of the member 16 will, through the action of the spring 14, result in a movement of the rod 13 in the opposite direction and a consequent upward movement of the rod 8.

rod 13 is i The applicationof the described movement to a power press, in combination with the magnet and circuit described consists in controlling by means (not shown) at the upper end of the rod 8 the trip whereby the fiy-Wheel and crankshaft are engaged to enable the plunger of the press to perform its working movement, this engagement not being permitted, for instance, until desired conditions obtain, such as freedom of the path of the'plunger from foreign bodies, the electric circuitnot being completed until such freedom is assured.

In a mechanical movement for use in the operation of power presses, the combi nation of a rod free to reciprocate inone plane, an intermittently-effective source of power, said rod being connected to said intermittently-effective source of power, the latterbeing adapted to move said rod in one direction; means for moving said rod in the opposite direction, said rod being formed with fa plurality of cam surfaces; and a second rod formed with a plurality of complementary cam surfaces adapted to engage with the cam' surfaces on the first named rod.

2. In a mechanical movement for use in the operation of power presses, the combination ofla rod free to reciprocate in one plane; a magnetizable movable member, said rod being connected with said magnetizable movable membe; a magnet disposed adj acently said member; an electric circuit within which said magnet is included; means for moving said rod in the direction opposite to that in which it is movedby the action of said magnet,said rod being formed with a plurality of cam surfaces; and a second rod free to reciprocate and formed witha plurality of cam surfaces adapted to engage with the cam surfaces of the first named ro d,, wh ereby the movement is positively locked at the end of the actuation in either directlon.
